LASER BASED AUDIO COMMUNICATION SYSTEM
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 2015, Vol 4, Issue 5
Abstract
This paper involves building a scaled down, simple laser communication system that is used to send audio signal s over a distance. The free space communication system used here consists of a transmitter that super imposes an audio signal into a light source. The receiver contains a photo detector and is connected only through an optical path with the transmitter , with air as the free space medium . The light source is a laser diode and the detector is a se miconductor - based photoresistor made of Cadmium Sulfide (CdS).
